Configuration Essentials
Configure at ~/.config/opencode/opencode-mem.jsonc:
Windows: %USERPROFILE%\.config\opencode\opencode-mem.jsonc (same .config\opencode directory as above — not AppData). Default storage resolves to %USERPROFILE%\.opencode-mem\data (the ~ form expands to your user home on Windows as well).
The plugin creates a full commented template at this path on first startup. For every setting and comment, see opencode-mem.example.jsonc.
